How to Use the PPF Calculator
Enter your annual deposit
Drag the slider or type the amount you plan to put in each financial year. The range is Rs. 500 to Rs. 1,50,000, which are the statutory minimum and maximum under the PPF Scheme, 2019.
Set your investment period
The default is 15 years, the statutory maturity of a PPF account. IF you plan to extend in five year blocks after maturity, THEN set 20, 25 or 30 years to model that.
Read the four outputs
Maturity Value is what you receive at the end. Total Invested is your own money. Interest Earned is the difference between the two. Return Multiple tells you how many times your deposits grew.
Check the assumption before you trust the number
The calculator holds the rate at 7.1% per annum for the whole period and assumes one deposit at the start of each financial year. The Ministry of Finance resets the PPF rate every quarter, so treat a 30 year horizon as a projection, not a promise.
What This PPF Account Calculator Does Differently
Most PPF account calculators stop at the maturity number. This one is built to answer the three questions that actually change your outcome. Does the timing of your deposit matter? It does, by Rs. 1,23,610 across 15 years. Does your bank or post office affect your rate? It does not, and the reason is worth understanding. What is 7.1% tax free genuinely worth against a taxable fixed deposit? For a 30% slab taxpayer, the same as a 10.32% FD that no bank offers. IF you only need the maturity figure, THEN the calculator above is enough. IF you want to know what to do differently, THEN the sections below are the ones to read.
What the PPF Interest Rate Calculator Is Assuming
A rate set by government, not by your bank
The Department of Economic Affairs notifies the PPF rate each quarter, guided by the Shyamala Gopinath Committee principle of the average 10 year government security yield plus a spread of 25 basis points. This is why a PPF interest rate calculator returns the same answer for SBI, HDFC Bank, ICICI Bank, Axis Bank, Punjab National Bank, Canara Bank and the post office.
Annual compounding, credited on 31 March
Interest accrues monthly on the lowest balance between the 5th and the last day of each month, but reaches your account only once a year, on 31 March. That single rule is why deposit timing matters more in PPF than in almost any other Indian savings product.
Tax free at all three stages
PPF carries EEE (Exempt, Exempt, Exempt) status. Deposits qualify for a deduction under Section 80C, renumbered as Section 123 by the Income Tax Act, 2025, but only under the old tax regime. Interest and maturity proceeds are exempt under Section 10(11) under both the old and the new regime, and no TDS (Tax Deducted at Source) is applied.
A rate that can move against you
The rate is reviewed quarterly and is not locked for the life of your account. It was 7.9% until March 2020 and 8.7% in 2013-14. IF the rate falls, THEN your maturity value falls with it. Holding 7.1% flat for 15 years is a modelling convention, not a forecast.
PPF at a Glance
How PPF Interest Is Calculated
Three rules govern every rupee of PPF interest.
- The balance that counts is the lowest balance between the 5th and the last day of the month. Money deposited after the 5th earns nothing that month, and money withdrawn during the month reduces the base for that month.
- Interest accrues monthly at one twelfth of the annual rate but is credited only once a year, on 31 March.
- Credited interest joins the principal and earns interest itself from the next year onward. This is why the interest line grows every year even when your deposit stays flat.
The PPF Formula
M: is the maturity value
P: is the annual deposit
i: is the interest rate as a decimal (0.071)
n: is the number of years.
The trailing (1 + i) is what makes it an annuity due. It accounts for each deposit being made at the start of the year rather than the end.
Worked example
Year one, with Rs. 1,50,000 deposited on 1 April at 7.1%. The lowest balance in each of the twelve months is Rs. 1,50,000, so interest is Rs. 1,50,000 multiplied by 7.1%, or Rs. 10,650, credited on 31 March.
Year two, with another Rs. 1,50,000 added on 1 April. The base becomes Rs. 1,60,650 plus Rs. 1,50,000, so interest is Rs. 22,056.
By year 15 the annual interest credit is Rs. 2,69,695, which is larger than the Rs. 1,50,000 you deposit that year. That crossover happens in year 11, and it is the entire argument for opening the account early rather than depositing more later.
PPF Return Calculator: What 7.1% Is Actually Worth
A maturity number on its own is not a return. Two adjustments make it comparable to anything else you own.
Against a taxable deposit
PPF interest is exempt under Section 10(11) and attracts no TDS. A bank fixed deposit is taxed at your slab. To match PPF's 7.1% tax free, a taxable FD would have to pay the following pre-tax rate.
| Your tax slab | Effective rate with 4% cess | Pre-tax FD rate needed to match PPF |
| 30% | 31.20% | 10.32% |
| 20% | 20.80% | 8.96% |
| 5% | 5.20% | 7.49% |
No Indian bank currently offers a retail fixed deposit anywhere near 10.32%. For a taxpayer in the 30% slab, PPF is the highest risk free post-tax return available on a rupee deposit, which is a fair part of the reason the Rs. 1,50,000 ceiling exists at all.
PPF Maturity Value Year Wise: The Full 15 Year Chart
The table below is what the calculator does internally, for the maximum deposit of Rs. 1,50,000 a year at 7.1%, with each deposit made at the start of the financial year. All figures are in rupees.
| Yr | Opening balance | Deposit | Interest credited | Closing balance |
| 1 | 0 | 1,50,000 | 10,650 | 1,60,650 |
| 2 | 1,60,650 | 1,50,000 | 22,056 | 3,32,706 |
| 3 | 3,32,706 | 1,50,000 | 34,272 | 5,16,978 |
| 4 | 5,16,978 | 1,50,000 | 47,355 | 7,14,334 |
| 5 | 7,14,334 | 1,50,000 | 61,368 | 9,25,701 |
| 6 | 9,25,701 | 1,50,000 | 76,375 | 11,52,076 |
| 7 | 11,52,076 | 1,50,000 | 92,447 | 13,94,524 |
| 8 | 13,94,524 | 1,50,000 | 1,09,661 | 16,54,185 |
| 9 | 16,54,185 | 16,54,185 | 1,28,097 | 19,32,282 |
| 10 | 19,32,282 | 1,50,000 | 1,47,842 | 22,30,124 |
| 11 | 22,30,124 | 1,50,000 | 1,68,989 | 25,49,113 |
| 12 | 25,49,113 | 1,50,000 | 1,68,989 | 28,90,750 |
| 13 | 28,90,750 | 1,50,000 | 2,15,893 | 32,56,643 |
| 14 | 32,56,643 | 1,50,000 | 2,41,872 | 36,48,515 |
| 15 | 36,48,515 | 1,50,000 | 2,69,695 | 40,68,209 |
Two things are worth noticing:
1. The interest credited in year 15 alone, Rs. 2,69,695, is larger than the Rs. 1,50,000 you deposit that year.
2. Your own money is still 55% of the closing balance at maturity, because interest only overtakes principal in year 18.
That is the strongest argument on this page for extending the account in five year blocks rather than closing it at 15.
PPF Withdrawal, Loan and Extension Rules
PPF is usually described as money locked away for 15 years. Three exits exist before then, each with a different trigger.
Partial withdrawal
Available from the seventh financial year. The amount is capped at 50% of the balance at the end of the fourth year immediately preceding the withdrawal year, or 50% of the balance at the end of the immediately preceding year, whichever is lower. One withdrawal per financial year, and it is tax free.
Loan against the balance
Available from the third to the sixth financial year, capped at 25% of the balance at the end of the second year preceding the loan year. Interest is charged at 1% above the prevailing PPF rate, so 8.1% today, and the principal must be repaid within 36 months. The loan window closes exactly when the withdrawal window opens.
Premature closure
Permitted after five complete financial years, and only for a life threatening illness of the account holder, spouse, dependent children or parents, for higher education, or on a change of residency status. The penalty is a 1% reduction in the interest rate applied across the entire life of the account, not just the remaining years.
Extension after maturity
At the end of 15 years you may extend in blocks of five years, with or without fresh contributions. IF you extend without contributions, THEN the balance continues to earn the notified rate and you may withdraw any amount once a year. IF you extend with contributions, THEN the extension form must be submitted within one year of the maturity date, and withdrawals across the five year block are capped at 60% of the balance standing at the start of that block.
Post Office PPF Calculator Vs Bank PPF Calculator: Is It Any Different?
A post office PPF calculator, an SBI PPF calculator and an HDFC or ICICI PPF calculator all produce the same number. This is not a shortcut on our part. It is how the scheme is built.
The Public Provident Fund (PPF) is a central government scheme governed by the PPF Scheme, 2019. The Ministry of Finance notifies a single interest rate every quarter, and that rate applies identically wherever the account is held. India Post cannot offer you 7.4% to win your deposit, and no bank can undercut it. The compounding method, the Rs. 500 minimum, the Rs. 1,50,000 ceiling, the 15 year term, the withdrawal rules and the Exempt-Exempt-Exempt (EEE) tax treatment all come from the same notification.
This is worth stating plainly because it is the opposite of how fixed deposits work. On a Fixed Deposit (FD), SBI, HDFC Bank and a small finance bank will quote three different rates for the same tenure, and choosing well is worth real money. On PPF the rate is 7.1% at all of them, including the post office, so the choice is purely operational.
So what does actually change when you choose where to open the account?
- Deposit convenience. IF your salary account sits with a bank that supports PPF standing instructions through net banking, THEN you can automate the April deposit and never lose the timing advantage. Post office accounts can be funded online through Department of Posts (DOP) internet banking, but the experience is less integrated.
- Account opening. Check whether the institution allows fully online opening with Aadhaar based electronic Know Your Customer (e-KYC), or still requires a branch visit.
- Statement access. A bank held PPF account usually appears in the same net banking dashboard as your savings account, which makes the annual interest credit easy to verify.
- Minor accounts. Check whether a minor's PPF account can be opened and viewed under the same login.
- Transfer. A PPF account can be moved between a post office and a bank, or between banks, without breaking the tenure or resetting the maturity date.
IF you already hold a post office PPF account, THEN there is no return advantage in moving it to a bank. IF you are opening a fresh account, THEN choose on the basis of how reliably you will be able to deposit before 5 April each year, because that habit is worth considerably more than the institution you pick.
One warning that applies wherever the account sits, and it carries the most expensive misunderstanding in PPF. The Rs. 1,50,000 ceiling is per person per financial year across all accounts, not per account. Depositing Rs. 1,50,000 in your own account and another Rs. 1,50,000 in your child's account as guardian does not double your interest. The excess earns nothing and is refunded without interest at the end of the year.
Three Things to Check Before You Commit to PPF
PPF sits inside a wider set of decisions. Each of these changes what PPF is actually worth to you.

Frequently Asked Questions
7.1% per annum, for the quarter from 1 July 2026 to 30 September 2026. The Ministry of Finance reviews small savings rates every quarter. The PPF rate has been unchanged at 7.1% since 1 April 2020.
Rs. 40,68,209, assuming the rate stays at 7.1% and each deposit is made at the start of the financial year. You would have deposited Rs. 22,50,000 of your own money, so Rs. 18,18,209 of the maturity value is interest, and all of it is tax free.
No. PPF is a central government scheme and the Ministry of Finance sets a single rate that applies at every post office and every authorised bank, including SBI, HDFC Bank, ICICI Bank, Axis Bank, PNB and Canara Bank. Where you hold the account affects convenience, not returns.
On or before 5 April of each financial year. Interest is calculated on the lowest balance between the 5th and the last day of each month, so a deposit made on 6 April earns nothing for that month. Depositing the full Rs. 1,50,000 in early April rather than spreading it across twelve months is worth about Rs. 1,23,610 over 15 years.
No. The ceiling is Rs. 1,50,000 per financial year and it applies to you as a person, not to each account. IF you also operate an account for a minor as guardian, THEN the two together cannot exceed Rs. 1,50,000. Any excess earns no interest and is refunded.
Partial withdrawal is allowed from the seventh financial year, once a year, capped at 50% of the balance at the end of the fourth preceding year or the immediately preceding year, whichever is lower. A loan is available from the third to the sixth year. Premature closure is permitted after five years only for specified medical, education or residency reasons, and carries a 1% interest penalty.
You can withdraw the full balance tax free, or extend the account in blocks of five years, with or without further contributions. IF you extend with contributions, THEN the extension form must be submitted within one year of the maturity date. IF you do nothing, THEN the account keeps earning interest but you cannot make fresh deposits.
No. Interest and maturity proceeds are exempt under Section 10(11) of the Income Tax Act under both the old and the new tax regime, and no TDS is deducted at any stage. The deduction on deposits under Section 80C, renumbered as Section 123 by the Income Tax Act, 2025, is available only under the old regime.
